Well I can't say it's perfect, but it's hilarious and somehow cute, so I think this icon would work perfectly as avatar. The only thing I think you might think about changing or at least improving a little is the bottom of it. I think it would be interesting to draw some sort of feet for this dragon, and maybe you could try to make it look less like a triangle. The animation of the wings it well made, as for the rotation you could add some more frames to make it look more fluid. As for the colours, I think that these basic colours (without shadings) are perfect for the way you decided to draw the dragon, it's a sort of childish style that I really adore. With childish I mean that it reminds me of the typical drawings and illustration created for babies and children, without too many details, really simple and basics.Great work.

oh no XD lols, you can use it in journals..but many people have been taking the dancing dragon icons, and using them as their Display picture. Some of them used dancing dragons, that i made for others XP, and some, don't even give credit XP you would tell how annoying that is lol
